v1.1.0 – Extended simulation scenarios and reproducible analysis pipeline

Authors/Creators

Description

Overview

This release updates the repository to reflect the analyses performed in the revised version of the manuscript comparing distance-based and model-based clustering methods for longitudinal psychiatric data.

The repository provides fully reproducible R scripts for both real data analyses and simulation experiments.

Major updates in this release

Simulation design extended

  • Added simulation scenarios with unbalanced group-size distributions, reflecting heterogeneity commonly observed in psychiatric longitudinal cohorts.
  • Implemented missing data mechanisms informed by the empirical missingness pattern observed in the PEPs cohort to increase the realism of the simulated datasets.

Improved computational pipeline

Simulation and model-fitting procedures were updated to support parallel execution using parLapply, substantially improving computational efficiency for large simulation experiments.

Repository reorganization

The repository structure has been reorganized to clearly separate real-data and simulation analyses:

1_Real_data_analysis
    1_1_functions.R
    1_2_analysis.R

2_Simulated_data_analysis
    2_1_functions.R
    2_2_analysis_balanced_clusters.R
    2_3_analysis_unbalanced_clusters.R

This structure improves transparency and reproducibility of the different analytical components.

Purpose of the repository

This repository supports methodological research on identifying trajectory-based response phenotypes in longitudinal psychiatric data and enables full reproducibility of the analyses reported in the accompanying manuscript.
